multiple power boards would probably be a problem. The current loop AREA from the driver OUT, through the gate resistor, into the gate leg of the mosfet, inside the mosfet to the source leg of the mosfet, and back to the gate driver ground must be as small as possible. That gets really hard to do when the distance from the driver to the mosfet gets big. Also, the gate driver would need to provide twice the gate charge if you included another power board, and it is already pushing it with 10 of IRFP4668.
